Culture Day (文化の日, Bunka-no-hi) is a national holiday held annually in Japan on November 3 for the purpose of promoting culture, the arts, and academic endeavor. Festivities typically include art exhibitions, parades, and award ceremonies for distinguished artists and scholars.
Since 1937, the award ceremony for the prestigious Order of Culture has been held on this day. Given by the Emperor himself to those who have significantly advanced science, the arts or culture, it is one of the highest honors bestowed by the Imperial Family.
Culture Day is statistically one of the clearest days of the year. Between 1965 and 1996, there have only been three years with rain occurring in Tokyo on Culture Day. (Wiki)
